Help with fileChooser

I want to use the file chooser,I want a menu Item (File) and the user clicks a menuitem ( open ) underneath that menu and then the file chooser screen comes up. What I have works but some how you see the Filechooser pane with out clicking open on the file menu. i eventually wan the frame to be tabbed so you would run the app click file then open and then it would process that file and out put data to the tabbed panels. How can I attach a file in this forum?
